An efficient, catalyst- and additive-free, visible-light-driven radical C3–H alkylation of quinoxalin-2(1H)-one derivatives has been developed. This reaction utilizes alkyl-NHP-esters as an alkyl radical donor and quinoxalin-2(1H)-one derivatives as an alkyl radical acceptor. The operationally simple protocol works under mild reaction conditions and tolerates a variety of functional groups. Furthermore
已开发出一种高效、无催化剂和添加剂、可见光驱动的自由基 C3-H 烷基化喹喔啉-2(1 H )-酮衍生物。该反应利用烷基-NHP-酯作为烷基自由基供体和喹喔啉-2(1 H )-酮衍生物作为烷基自由基受体。操作简单的协议在温和的反应条件下工作,并容忍各种功能组。此外,该方法的合成效用已成功用于合成生物学相关的 C3-烷基取代喹喔啉-2(1 H )-一衍生物
